Planys Technologies, a deep-tech firm specializing in underwater robotics and advanced inspection solutions, announced on Dec. 4, 2025, that it has raised ₹100 crore in primary funding to accelerate its global expansion and launch its defence-focused subsidiary, Planys Ark. The investment round was led by marquee investors Ashish Kacholia and Lashit Sanghvi, with participation from existing backers including Pratithi Investment, Samarthya Investment Advisors, 3i Partners, Letsventure, and several angel investors. The round also facilitated exits for early stakeholders, reflecting significant value creation since the company’s inception.
“This capital infusion marks a pivotal step in Planys’ journey,” said Tanuj Jhunjhunwala, CEO and Co-Founder. “It enables us to enhance our solutions for some of the world’s largest organisations while concurrently developing India’s next generation of unmanned underwater systems. Through our defence arm — Planys Ark — we are intensifying our focus on high-impact defence opportunities.”
Planys is deepening its core industrial vertical with a new generation of underwater robotic systems, including hybrid ROVs, robotic crawlers, and an AI-powered 3D Inspection Twin for testing critical infrastructure. Its upcoming internationally certified, explosion-proof ROV, the TankRover, enables in-service inspection of hydrocarbon storage tanks, improving safety, increasing inspection frequency, and reducing downtime and operational costs. The company claims to be the only global provider of submersible robotic vehicles capable of underwater concrete testing for infrastructure applications.
Vineet Upadhyay, CTO and Co-Founder, said, “With Planys Ark, we are fast-tracking a new generation of indigenous underwater systems designed to elevate India’s defence capabilities to global standards. Our fully India-built technologies enable mission-ready, customisable UUV solutions for complex operational scenarios.” Upadhyay added that the company plans to establish a state-of-the-art unmanned underwater vehicle (UUV) production facility in South Chennai, featuring advanced fabrication and underwater testing infrastructure.
Founded in 2015 by IIT Madras alumni Tanuj Jhunjhunwala and Vineet Upadhyay along with Professors Prabhu Rajagopal and Krishnan Balasubramaniam, Planys has emerged as a category creator in advanced underwater systems. Its proprietary platforms are engineered for environments historically considered inaccessible, including ultra-turbid waters and complex structural testing applications. The company holds 21 granted patents with 15 more filed, underlining its strong innovation and IP portfolio.
Planys has clocked over 25,000 hours of operational deployment across 500 sites in more than 10 countries, serving 150+ users. Its global footprint spans Singapore, Brunei, Saudi Arabia, the UAE, Qatar, Oman, and the Netherlands, with clients including Reliance Industries, IOCL, BPCL, MSRDC, Indian Railways, ExxonMobil, Shell, Saudi Aramco, and SABIC.
Lead investor Ashish Kacholia said, “Planys has demonstrated exceptional technology depth and strong commercial traction. Its in-house platforms uniquely position the company to lead across industrial and defence applications.”
Planys is also expanding internationally through strategic partnerships. Collaboration with Applus Velosi in Qatar provides access to high-value industrial clients, while participation in HUB71’s deep-tech cohort in Abu Dhabi offers global ecosystem linkages. These alliances are expected to help the company scale inspection delivery capabilities, commercialise AI-driven NDT products, accelerate unmanned systems manufacturing, and serve industrial and defence customers with India-built, world-class underwater technology.
With this funding, Planys aims to consolidate its leadership in industrial inspection and establish a robust foothold in defence.
